To LZZ whom it may concern/s Be it known thatl I, OSCAR C. NICKERSON, a citizen'of vthe United States, residing at Chatham, inthe Vcounty of Barnstable and State of Massachusetts, have invented certain new and useful Improvements in Life-Boat Wagons; and I do hereby declare the following to be a full, clear, and "exact description of the invention, suchV as will enable others skilled in the art to which it appertains' to make and use ih'e same.

This invention relates to lifeboat wagons; and it consists in the novel construction and combinationV of the 'parts hereinafter fully described and claimed.

In the drawings, Figure l is a side view of the wagon with the wheels removed. Fig. 2 is a plan view of the wagon. Fig. 3 is a rear view of vthe rear axle. Fig. 4 is a cross-section through the tongues, showing also the bolster' of the front axle.V

A is the rear axle, provided with wheels a in the usual manner.

B is a bolster, and C is the front axle provided with wheels c and pivoted under the.

bolster B in any approved way. v

D represents portions of the shafts secured to the front axle.

The bolster B is provided with stationary chocks d, which are curved to t the bows of the boat closely and which hold the vboat in position.

E is a tongue secured to the rear axle A and strengthened by inclined braces e.

F is a tongue secured to the bolster B and arranged to slide over the tongueE. s v. f-

G represents two guide-straps for` thegslidable tongue F. These straps are secured to the tongues, and one of them is provided with a roller f at its upper part for the tongue F to bear against. Y

The rear axle A is provided with slidable ehooks g, which [it between it and the stern portion of the keel'ofthe boat. These chocks are slid back and forth on the axle and may be secured to it inA any approved way. The middle part of the rear axle is provided with a notch H, and h is a roller journaled in the notch H. The boat rests on, the -lsaid roller h and on the chocks of the bolster.

The slidable tongue is provided with a series of holes 7c, and K'is agpin which engages with a hole in the lower tongueE and with either of theV holes k. Y

' "Whe'ntheboat'is' to be unloaded, the rear wheels a. are locked 'and the pin Kis'removed. The slidable checks g are withdrawn to free the stern of the boat and the horses are backed. The boat slides over the roller h until its center of gravity passes over it. The boat then tilts up until `its stern end rests on the ground. .The rear wheels are then unlocked and thewhole wagon isV drawn forwardyfrom under the boat, which is unloaded Vfront axle-bolster provided with a tongue F which slides above the tongue E; of chocks wsecured to the said bolster, slidable chocks carried by the rear axle, a rollerl h for the boat-keel arranged in the notch H, a guide secured tothe free end of the upper tongue F and engaging with the lower tongue E, a forked guide secured to the lower tongue E and st'raddling the upper tongue F, a roller vjournaled in the said forked guide and bearingagainst the upper side ofthe tongue F, 'and means for connecting the said tongues together, substantially as setforth.
